Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance details as specified in official documentation. Ensure handling procedures account for moisture sensitivity levels indicated in the datasheet. Validate package integrity upon receipt to prevent damage to the PLCC-44 pins during installation.
Selection Notes
Select this component when specific integration of virtual EEPROM and Flash memory is required within an 8-bit architecture. Consider the 10 MHz maximum clock speed and 37 available I/O lines for interface requirements. Evaluate the PLCC-44 package suitability for the target PCB layout. Verify that the 2.7 V to 5.5 V operating voltage aligns with the system power design constraints.
Part Context
This part belongs to the COP8SCR9 family of 8-bit CMOS Flash microcontrollers. The series is characterized by its combination of Flash memory and virtual EEPROM capabilities. Texas Instruments acquired the COP8 line from National Semiconductor.
